Abstract

A power divider has a microstripline circuit with bandpass filters at each output that are lumped element printed bandpass filters. The filters widen the isolation bandwidth of the divider. Power dividers can be reversed for use as power combiners.
Previous dividers are too large or they do not have a sufficiently wide bandwidth.
